Accelerating PFAS Treatment With Modular Systems

Per- and polyfluoroalkyl substances (PFAS) treatment often must move faster than traditional infrastructure delivery allows. Onterris provides modular treatment systems that deploy quickly, adapt to site conditions and scale as treatment needs change. From urgent response projects to longer-term installations, we help organizations treat contaminated water with practical systems designed for performance, flexibility and speed. With a strong regulatory foundation, we help clients move with greater confidence as water conditions, compliance demands and delivery timelines evolve.

The SORBIX Modular (M) Series adds containerized treatment systems built for rapid PFAS deployment across a wide range of site conditions. Available in Premium, Standard and Essential configurations, the M Series supports single train treatment flows up to 1.25 MGD and can be tailored with customizable pretreatment and lead-lag ion exchange treatment. The product line has been used for PFAS-impacted groundwater, stormwater and drinking water projects internationally.
